In a class the other day I was informed about a 3rd level of Hazard listed by ASSE for backflow prevention. The 3rd level is Extreme High Hazard and includes systems that include Ethelyne Glycol, and Water Cooled Sewage Pumps. When these situations arise many people will install a ASSE 1013 Reduced Pressure Backflow Preventer however it now calls for an AIR GAP! Just an FYI for those of you that are into this kind of stuff.
If you need more information on this or anything having to do with Backflow Prevention and ASSE codes feel free to call Winstel Controls @ 513-251-4343 or visit www.winstelcontrols.com.
